A guidewire locking device assembly (200) including a guidewire tube (250) with a tubular passage therethrough having a first diameter and a distal end including a collar (260) having a second diameter larger than the first diameter. A guidewire (202) having a third diameter, smaller than the first diameter is disposed within the tubular passage. When a guidewire locking device (216) is disposed within the guidewire tube distal end in a first position with its biasing member in the tubular passage, the at least one finger (220) is biased by the tubular passage into frictional engagement with the guidewire; when disposed in a second position in the collar, the at least one finger is disposed away from frictional engagement with the guidewire.
